A company uses Microsoft Defender for Cloud's Just-In-Time (JIT) VM access to manage RDP connections to a critical jump-box virtual machine. The company has a CI/CD pipeline running on Azure DevOps agent pools that needs to periodically RDP into this VM to deploy software. The agent pool's source IP addresses are dynamic and change frequently. They want the pipeline to automatically request JIT access before each deployment without manual intervention. Which approach should they implement?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Best answer
Use the Azure REST API with a managed identity assigned to the DevOps agent to request JIT access, specifying the agent's current source IP address
The REST API endpoint for JIT allows programmatic requests. A managed identity on the agent (or virtual machine running the agent) provides secure authentication without secrets. The pipeline can fetch its current outbound IP and request JIT access for the required time.
Distractor review
Create a JIT access rule in Defender for Cloud with a scheduled time window that matches the pipeline's deployment schedule
Scheduling a JIT rule to open the port during expected times undermines the zero-trust principle of JIT. It leaves the port open for the entire window, even if no deployment occurs, increasing the attack surface.
Distractor review
Configure a PowerShell script in the pipeline to modify the network security group (NSG) to allow the agent's IP during deployment
Directly modifying NSGs bypasses JIT's centralized approval and auditing. It is less secure and harder to manage. The JIT REST API is the intended way to automate access while maintaining security controls.
Distractor review
Assign a static public IP to the Azure DevOps agent and add that IP to the JIT allowed list permanently
This would effectively disable JIT for that IP by making it always allowed, which violates the principle of just-in-time access.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-500 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Use the Azure REST API with a managed identity assigned to the DevOps agent to request JIT access, specifying the agent's current source IP address — The Azure REST API provides a programmatic way to request JIT access for a VM. By assigning a managed identity (system-assigned or user-assigned) to the Azure DevOps agent (or the compute resource hosting the pipeline), the pipeline can authenticate to Azure and call the REST API to request JIT access. The request can specify allowed source IPs (e.g., the agent's current IP) and a time window. This fully automates the process. Creating a permanent scheduled rule defeats the purpose of JIT. NSG modifications are manual and not recommended.
